MathPapa's goal is to help you learn algebra step-by-step. Robert Ikeda holds a Stanford University PhD in Computer Science, University of California, San Diego Bachelor's in Electrical Engineering; Minor in Mathematics, and competed in the United States Math Olympiad (USAMO). He also has two years of math tutoring experience. Priscilla Pham graduated from Stanford University with Bachelor's and Master's degrees in Computer Science. She has also been mentoring in computer science and software engineering for five years. We look forward to making it easier and more fun to learn algebra online. Sample: Try the calculator by clicking any example below. Fractions Adding Fractions: 1/3 + 1/4 Multiplying Fractions: (1/3) * (3/4) Exponents Multiplying Exponents: 2^3 * 2^4 Dividing Exponents: 2^3 / 2^5 Exponents: (2^3)^4 Polynomials Adding Polynomials: x^2 + x + 2 + (2x^2 - 2x) Multiplying Polynomials: (x+1)(x+2) Squaring Polynomials: (x+3)^2 Graphing Functions Parabola: y=2x^2+1 Inequalities: y>3x+5; y<=x Line: y=2x+3 Evaluating Expressions Evaluate x^2+2x for x=5: x^2+2x @ x=5 Evaluate 2x^2+2y for x=5, y=3: 2x^2+2y @ x=5, y=3 Solving Equations Solve x+5=8: x+5=8 Solve system x+y=7 and x+2y=11: x+y=7; x+2y=11 Check answer (3,4) for equations x+y=7 and x+2y=11: x+y=7; x+2y=11 @ x=3,y=4 Solving Inequalities Solve 2x+3>23: 2x+3>23 Solve x>2 and x+3<7: x>2 and x+3<7 Solve |2x+3|>=23: |2x+3|>=23
